Indications

As has been found, the compounds of formula 1 are characterised by theirwide range of applications in the therapeutic field. Particular mentionshould be made of those applications for which the compounds accordingto the invention of formula 1 are preferably suited on account of theirpharmaceutical efficacy as PDE4 inhibitors. Examples include respiratoryor gastrointestinal diseases or complaints, inflammatory diseases of thejoints, skin or eyes, cancers, and also diseases of the peripheral orcentral nervous system.

Particular mention should be made of the prevention and treatment ofdiseases of the airways and of the lung which are accompanied byincreased mucus production, inflammations and/or obstructive diseases ofthe airways. Examples include acute, allergic or chronic bronchitis,chronic obstructive bronchitis (COPD), coughing, pulmonary emphysema,allergic or non-allergic rhinitis or sinusitis, chronic rhinitis orsinusitis, asthma, alveolitis, Farmer's disease, hyperreactive airways,infectious bronchitis or pneumonitis, paediatric asthma, bronchiectases,pulmonary fibrosis, ARDS (acute adult respiratory distress syndrome),bronchial oedema, pulmonary oedema, bronchitis, pneumonia orinterstitial pneumonia triggered by various causes, such as aspiration,inhalation of toxic gases, or bronchitis, pneumonia or interstitialpneumonia as a result of heart failure, irradiation, chemotherapy,cystic fibrosis or mucoviscidosis, or alpha1-antitrypsin deficiency.

Also deserving special mention is the treatment of inflammatory diseasesof the gastrointestinal tract. Examples include acute or chronicinflammatory changes in gall bladder inflammation, Crohn's disease,ulcerative colitis, inflammatory pseudopolyps, juvenile polyps, colitiscystica profunda, pneumatosis cystoides intestinales, diseases of thebile duct and gall bladder, e.g. gallstones and conglomerates, for thetreatment of inflammatory diseases of the joints such as rheumatoidarthritis or inflammatory diseases of the skin and eyes.

Preferential mention should also be made of the treatment of cancers.Examples include all forms of acute and chronic leukaemias such as acutelymphatic and acute myeloid leukaemia, chronic lymphatic and chronicmyeloid leukaemia, and bone tumours such as osteosarcoma and all typesof glioma such as oligodendroglioma and glioblastoma.

Preferential mention should also be made of the prevention and treatmentof diseases of the peripheral or central nervous system. Examples ofthese include depression, bipolar or manic depression, acute and chronicanxiety states, schizophrenia, Alzheimer's disease, Parkinson's disease,acute and chronic multiple sclerosis or acute and chronic pain as wellas injuries to the brain caused by stroke, hypoxia or craniocerebraltrauma.

Particularly preferably the present invention relates to the use ofcompounds of formula 1 for preparing a pharmaceutical composition forthe treatment of inflammatory or obstructive diseases of the upper andlower respiratory tract including the lungs, such as for exampleallergic rhinitis, chronic rhinitis, bronchiectasis, cystic fibrosis,idiopathic pulmonary fibrosis, fibrosing alveolitis, COPD, chronicbronchitis, chronic sinusitis, asthma, Crohn's disease, ulcerativecolitis, particularly COPD, chronic bronchitis and asthma.

It is most preferable to use the compounds of formula 1 for thetreatment of inflammatory and obstructive diseases such as COPD, chronicbronchitis, chronic sinusitis, asthma, Crohn's disease, ulcerativecolitis, particularly COPD, chronic bronchitis and asthma.

It is also preferable to use the compounds of formula 1 for thetreatment of diseases of the peripheral or central nervous system suchas depression, bipolar or manic depression, acute and chronic anxietystates, schizophrenia, Alzheimer's disease, Parkinson's disease, acuteand chronic multiple sclerosis or acute and chronic pain as well asinjuries to the brain caused by stroke, hypoxia or craniocerebraltrauma.

An outstanding aspect of the present invention is the reduced profile ofside effects. This means, within the scope of the invention, being ableto administer a dose of a pharmaceutical composition without inducingvomiting, preferably nausea and most preferably malaise in the patient.It is particularly preferable to be able to administer a therapeuticallyeffective quantity of substance without inducing emesis or nausea, atevery stage of the disease.

Combinations

The compounds of formula 1 may be used on their own or in conjunctionwith other active substances of formula 1 according to the invention. Ifdesired the compounds of formula 1 may also be used in combination withother pharmacologically active substances. It is preferable to use forthis purpose active substances selected for example from amongbetamimetics, anticholinergics, corticosteroids, other PDE4-inhibitors,LTD4-antagonists, EGFR-inhibitors, MRP4-inhibitors, dopamine agonists,H1-antihistamines, PAF-antagonists and PI3-kinase inhibitors or doubleor triple combinations thereof, such as for example combinations ofcompounds of formula 1 with one or two compounds selected from among

-   -   betamimetics, corticosteroids, PDE4-inhibitors, EGFR-inhibitors        and LTD4-antagonists,    -   anticholinergics, betamimetics, corticosteroids,        PDE4-inhibitors, EGFR-inhibitors and LTD4-antagonists,    -   PDE4-inhibitors, corticosteroids, EGFR-inhibitors and        LTD4-antagonists    -   EGFR-inhibitors, PDE4-inhibitors and LTD4-antagonists    -   EGFR-inhibitors and LTD4-antagonists    -   CCR3-inhibitors, iNOS-inhibitors (inducible nitric oxide        synthase-inhibitors), (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin        (hereinafter referred to as “BH4”) and the derivatives thereof        as mentioned in WO 2006/120176 and SYK-inhibitors (spleen        tyrosine kinase-inhibitors)    -   anticholinergics, betamimetics, corticosteroids, PDE4-inhibitors        and MRP4-inhibitors.
